Multiplex Mentor cover clip

Replacement clip to hold the front/cockpit cover in place.

Update 24-10-18:
There are two versions:
- clip rotated = almost as original clip, to be printed on its side.
- clip modified flat = clip with one flat side.I found that this one is easier to print (flat on the bed) and still locks in place on te 'female clip' in the plane.

Please let me know if you try one.
